- Abstract:
-
This GIS tidal datalayer contains National Oceanic and Atmospheric Administration (NOAA) tidal information for those areas with tidal current speeds greater than 3 knots in Massachusetts waters. The information was obtained from tidal current tables published by NOAA for both reference and subordinate tidal gaging stations located in waters along the Massachusetts coastline. The criteria of 3 knots or greater was used as a minimum standard at which tidal in stream energy conversion devices can operate at based on current technology and proposed design.
- Purpose:
-
This datalayer was created to assist in locating foreseeable siting areas for future energy facilities located within Massachusetts state waters and federal waters up to 200 miles from the Massachusetts coastline. Component of Massachusetts Office of Coastal Zone Management Human Uses database.
- Supplemental_Information:
-
The database contains tide and/or tidal current predictions and associated information produced by and obtained from the Dept. of Commerce, NOAA, National Ocean Service. These predictions satisfy all U.S. Coast Guard requirements including: 33CFR CH. I (7-1-91 Edition), 164.33 Charts and Publications.

-
- Attribute_Accuracy_Report:
-
Attribute accuracy was tested by interactively querying and verified on the screen, and compared against a master set of valid attributes. Locations were derived from hardcopy coordinate values as listed in the citation section of this document. The accuracy of the published coordinates compared to the actual tidal gage location is unknown.
- Quantitative_Attribute_Accuracy_Assessment:
-
- Attribute_Accuracy_Value: n/a
- Logical_Consistency_Report:
-
Point data was entered as a comma delimited text file based on latitude and longitude values, and converted to NAD 83 Massachusetts Mainland meters projection using a commercially accepted coordinate conversion program. Subsequent testing of the data was not performed.
- Completeness_Report:
-
All displayed features were mapped based upon the results of a review of NOAA tidal current information for reference and subordinate gaging stations located in coastal waters of Massachusetts, where available. Those station locations that resulted in a maximum flood or maximum ebb value of 3 knots or greater was retained for this dataset. The criteria of 3 knots or greater was used as a minimum standard at which tidal in stream energy conversion devices can operate at based on current technology and proposed design.

- Horizontal_Positional_Accuracy_Report:
-
Horizontal positional accuracy for this digital data was tested by visual comparison of the attribute using NOAA georeferenced raster base maps (chart nos. 13246, 13218, 13237) against tabulated location names. There was no other testing of the data.

- Process_Description:
-
Original latitude and longitude coordinates for tidal currents greater than 3 knots are NOAA reference and subordinate station locations along the Massachusetts coast, as tabulated in Table 2 of Atlantic Coast of North America Tidal Current Tables. The latitude and longitude coordinates were tabulated in comma delimited text file. A conversion of coordinates was made to NAD 83 MA State Plane Mainland with CorpsCon, a U.S. Army Corps of Engineers coordinate conversion program.
